“We are updating our 777 cabins to bring us into line with many of our competitors and allow us to offer even more low fares,” said a spokeswoman from British Airways. “We will begin our refit of the aircraft early in 2018, starting with our Gatwick 777 fleet.”

The update, which would make it possible for British Airways to offer cheaper seats than budget carrier Norwegian on select routes, will also include entertainment systems with larger screens.

Current seat width in economy on the 777s is 17.5 inches, according to SeatGuru. The airline said space in the aisles will likely be tighter due to the addition.

The airline did not confirm whether or not they are considering adding additional restrooms, which could also affect customer comfort.
